Reflections about holographic and non-holographic acquisition of surface topography
Gerd Häusler, Florian Willomitzer
Recording and (computational) processing of complex wave fields offers a vast realm of new optical methods. Also for optical 3D-metrology. We discuss fundamental similarities and d…
Single-shot 3D motion picture camera with a dense point cloud
Florian Willomitzer, Gerd Häusler
We introduce a method and a 3D-camera for single-shot 3D shape measurement, with unprecedented features: The 3D-camera does not rely on pattern codification and acquires object sur…
Better 3D Inspection with Structured Illumination Part I: Signal Formation and Precision
Zheng Yang, Alexander Kessel, Gerd Häusler
For quality control in the factory, 3D-metrology faces increasing demands for high precision and for more space-bandwidth-speed-product SBSP (number of 3D-points/sec). As a potenti…
Single-shot 3D sensing with improved data density
Florian Willomitzer, Svenja Ettl, Christian Faber +1
We introduce a novel concept for motion robust optical 3D-sensing. The concept is based on multi-line triangulation. The aim is to evaluate a large number of projected lines (high…
Fast and accurate Deflectometry with Crossed Fringes
Yuankun Liu, Evelyn Olesch, Zheng Yang +1
Phase Measuring Deflectometry (PMD) acquires the two components of the local surface gradient via a sequence of two orthogonal sinusoidal fringe patterns that have to be displayed…
Hand-guided 3D surface acquisition by combining simple light sectioning with real-time algorithms
Oliver Arold, Svenja Ettl, Florian Willomitzer +1
Precise 3D measurements of rigid surfaces are desired in many fields of application like quality control or surgery. Often, views from all around the object have to be acquired for…
